[0002] In industries such as chemical, pharmaceutical, food, and mining, large quantities of high-viscosity, high-solids-content materials (such as traditional Chinese medicine extracts, chemical slurries, food sauces, and mine tailings slurries) need to be stored or processed in tanks.

[0003] Due to their inherent characteristics, these materials are highly susceptible to stratification (forming a hard sediment layer at the bottom) and adhesion to the walls during settling or transportation, directly impacting production efficiency and product quality. Sedimentation leads to poor material uniformity, affecting the stability of drug efficacy; adhesion to the walls causes waste and pollution, and can also cause cross-contamination due to mold growth and oxidation of residual materials. Particulate materials (such as mineral slurry and traditional Chinese medicine residue slurry) are prone to clogging in conveying pipelines and storage tank inlets, requiring machine shutdown for cleaning; traditional mixing devices have gaps between the agitator and the tank wall, making it impossible to remove adhered materials, requiring periodic manual entry into the storage tank for cleaning (labor-intensive and posing safety risks in a confined space).

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This embodiment of the present invention provides a spiral flow guiding and anti-sedimentation stirring device for the inner wall of a storage tank, comprising: The feeding assembly 100 includes a base 101, a bracket 102 fixedly connected to the side wall of the base 101, a hopper 103 fixedly connected to the end of the bracket 102, a transfer pipe 104 adapted to be installed at the bottom of the hopper 103, and a storage tank 105 fixedly connected to the end of the transfer pipe 104. The discharge port at the bottom of the hopper 103 is connected to the inlet at the end of the storage tank 105 through the transfer pipe 104. A valve for use with the storage tank 105 is encapsulated in the middle of the transfer pipe 104. The mixing assembly 200 includes a main shaft 201 rotatably connected to the side wall of the storage tank 105, a bevel gear 202 adapted to be installed at the end of the main shaft 201, a connecting ring 203 rotatably installed on the inner wall of the storage tank 105, a mixing rod 204 fixedly connected to the end of the connecting ring 203, and a main scraper 205 fixedly connected to the end of the mixing rod 204. The side wall of the end of the main scraper 205 is in sliding contact with the inner wall of the storage tank 105. The teeth on the side wall of the bevel gear 202 mesh with the rack on the side wall of the connecting ring 203. The upper end of the connecting ring 203 has a beveled structure, and the beveled edge of the upper end of the connecting ring 203 extends to the inner wall of the storage tank 105.

[0019] The feeding assembly 100 is responsible for stably conveying the material to be mixed to the storage tank. The base 101 provides an installation benchmark for the entire equipment. The bottom outlet of the hopper 103 is connected to the end inlet of the storage tank 105 through the adapter pipe 104, forming a material conveying channel. The valve (manual or electric shut-off valve) encapsulated in the middle of the adapter pipe 104 can control the material conveying volume to adapt to different mixing requirements. The mixing assembly 200 ensures uniform mixing of materials without dead corners through a combination of rotational mixing, wall scraping, and spiral guiding. The mixing rod 204 is evenly fixed at the end of the connecting ring 203, and the main scraper 205 is fixed at the end of the mixing rod 204. When the connecting ring 203 rotates, the mixing rod 204 moves in a circular motion, forming a spiral mixing of the material in the tank. At the same time, the main scraper 205 slides close to the inner wall of the storage tank to scrape off the material adhering to the tank wall (preventing local sedimentation and agglomeration). The upper end of the connecting ring 203 has a beveled structure that extends to the inner wall of the storage tank. This can guide the falling material to slide into the tank along the bevel, preventing the material from directly impacting the tank wall and causing adhesion.

[0020] Specifically, a stirring motor 206 is fixedly connected to the side wall of the base 101. The output shaft end of the stirring motor 206 and the end of the main shaft 201 are equipped with matching sprockets 207, and the two sets of sprockets 207 are connected by chain drive.

[0021] When the stirring motor 206 is running, it drives the main shaft 201 to rotate via the sprocket 207 and chain drive, providing power for stirring. The teeth of the bevel gear 202 mesh with the side wall rack of the connecting ring 203 rotatably mounted on the inner wall of the storage tank 105, forming a "bevel gear-rack" transmission: the rotation of the main shaft 201 drives the bevel gear 202 to rotate, which in turn drives the connecting ring 203 to rotate circumferentially along the inner wall of the storage tank 105.

[0022] Furthermore, a support seat 208 is fixedly connected to the base 101. The support seat 208 is sleeved on the outside of the stirring motor 206. The end of the main shaft 201 is rotatably connected to the side wall of the support seat 208, and the side wall of the bracket 102 is connected to the side wall of the support seat 208 by bolts.

[0023] The support seat 208 on the side wall of the base 101 is used to shield and protect the stirring motor 206, while maintaining the stability of the stirring motor 206 position. It can also provide a stable rotating connection base for the main shaft 201, ensuring the smooth rotation of the main shaft 201.

[0024] Furthermore, the stirring assembly 200 also includes a support rod 209 inserted into the top of the support base 208, a lower locking block 210 fixedly connected to the end of the support rod 209, an upper locking block 211 fixedly connected to the end of the lower locking block 210, and a vibration motor 212 fixedly connected to the end of the upper locking block 211. The lower locking block 210 and the upper locking block 211 are engaged with each other and locked onto the side wall of the adapter pipe 104. A spring 213 is sleeved in the middle of the support rod 209. One end of the spring 213 is in elastic contact with the top of the support base 208, and the other end of the spring 213 is in elastic contact with the bottom of the lower locking block 210. A nut is installed at the bottom of the support rod 209 below the support base 208.

[0025] The support base 208 has a support rod 209 inserted into its top, which can slide up and down along the support base 208. The end of the support rod 209 is fixed with a lower locking block 210, which cooperates with the upper locking block 211 to form an annular locking groove, locking onto the side wall of the transfer pipe 104. The upper locking block 211 is fixed with a vibration motor 212, and a spring 213 is sleeved in the middle of the support rod 208 (both ends are in elastic contact with the top of the support base and the bottom of the lower locking block, respectively). When the vibration motor 212 is running, it drives the transfer pipe 104 to vibrate through the lower locking block 210 and the upper locking block 211. The spring 213 buffers and avoids violent impact, which can prevent materials from adhering and clogging inside the transfer pipe 104 (especially suitable for sticky materials).

[0026] It should be noted that the feeding assembly 100 also includes a secondary shaft 106 encapsulated at the end of the adapter tube 104, an auxiliary motor 107 fixedly connected to the side wall of the adapter tube 104, and a secondary scraper 108 fixedly connected to the end of the secondary shaft 106, the end of the secondary scraper 108 slidingly contacting the inclined surface of the side wall of the connecting ring 203.

[0027] The auxiliary motor 107 drives the secondary shaft to rotate, which in turn drives the secondary scraper 108 to rotate. The end of the secondary scraper 108 slides in contact with the upper inclined edge of the connecting ring 203 in the storage tank, which can scrape off the material adhering to the inclined surface of the connecting ring (to avoid material accumulation affecting the rotation of the connecting ring).

[0028] Preferably, the feeding assembly 100 further includes a screen 109 rotatably installed inside the hopper 103, a feeding motor 110 fixedly connected to the side wall of the hopper 103, and a lever 111 adapted to be installed at the end of the output shaft of the feeding motor 110, with the end of the lever 111 inserted into the middle of the screen 109.

[0029] The screen 109 is used to filter large impurities in the material to prevent blockage of subsequent pipes. A lever 111 is installed at the end of the output shaft of the feeding motor 110 on the side wall of the hopper. The end of the lever 111 is inserted into the middle of the screen 109. When the feeding motor 110 drives the lever 111 to rotate, it can move the material on the screen 109 to prevent impurities from accumulating and blocking the mesh. At the same time, it helps the material fall into the bottom of the hopper 103 through the mesh.

[0030] During use, the speed of the stirring motor 206, the vibration frequency of the vibrating motor 212, and the opening and closing degree of the valve are set according to the material characteristics (viscosity, particle size) to control the feeding speed. The material to be stirred is poured into the hopper 103, the feeding motor 110 is started, and the lever 111 rotates with the motor, pushing the material through the screen 109. The filtered material is collected at the bottom of the hopper.

[0031] Open the valve in the middle of the transfer pipe 104, and the material flows along the transfer pipe to the storage tank 105 under the action of gravity; at the same time, start the vibration motor 212, and the vibration is transmitted to the transfer pipe through the lower clamping block 210 and the upper clamping block 211, so that the pipe vibrates slightly (the spring 213 buffers to avoid resonance) to prevent the material from sticking to the pipe wall and causing blockage; the auxiliary motor 107 drives the secondary shaft 106 to rotate, which drives the secondary scraper 108 to scrape the upper inclined edge of the connecting ring 203 to prevent the material from accumulating on the inclined edge and ensure that the material slides smoothly into the tank.

[0032] Start the stirring motor 206. The output shaft of the stirring motor 206 drives the main shaft 201 to rotate through the sprocket 207 and the chain. The bevel gear 202 at the end of the main shaft rotates accordingly. Through meshing with the rack on the side wall of the connecting ring 203, it drives the connecting ring to run along the inner wall of the storage tank 105.

[0033] When the connecting ring 203 rotates, it drives the stirring rod 204 to make a circular motion, forming a spiral stirring of the material in the tank, so that the material is mixed evenly; at the same time, the main scraper 205 at the end of the stirring rod 204 slides close to the inner wall of the storage tank, scraping off the material adhering to the tank wall (to avoid local sedimentation and clumping), and the scraped-off material re-participates in the stirring, ensuring that there are no dead corners in the tank.

[0034] In summary, the connecting ring drives the stirring rod to form a spiral stirring zone. Combined with the real-time scraping of the tank wall by the main scraper, it solves the problem of "bottom sedimentation and wall adhesion" in traditional stirring. It is especially suitable for materials with high viscosity and high particle content. The screen filters large impurities, the lever prevents the mesh from clogging, the vibrating motor eliminates pipe adhesion, and the secondary scraper cleans the inclined edge of the connecting ring, forming a multi-stage anti-clogging system. This improves the equipment's adaptability to viscous and granular materials. The stirring components can operate intermittently during material storage, avoiding stratification caused by long-term static storage.
